>> In D-T fusion reaction, D2 (duterium) and T2(tritium) are used as fuel gas. The exhaust gas of nuclear fusion includes hydrogen isotopes Q2 (Q means H, D or T), tritiated components (CQ4 and Q2O), CO, CO2, etc. All of hydrogen isotopes should be recovered before released to the atmosphere. This study focused on the recovery of hydrogen isotopes from CQ4 and Q2O. Two kinds of experiments were conducted to investigate the catalytic reaction characteristics of SMR (Steam Methane Reforming) and

... GS (Water Gas Shift) reactions using Pt catalyst. First test was performed to convert CH4 into H2 using 6% CH4, 6% CO / Ar feed gas. In the other test, 100% CO gas was used to convert H2O into H2 at various reaction conditions (reaction temperature, S/C ratio, GHSV). As a result of the first test, CH4 and CO conversion were 41.6%, 57.8% respectively at 600°C, S/C ratio 3, GHSV 2000 hr -1 . And CO conversion was 72% at 400°C, S/C ratio 0.95, GHSV 333 hr -1 in the second test.
